College Works Painting on the Science Behind Exterior Paint Jobs

College Works Painting explains that an exterior paint job takes a significant amount of work. Whether it is a DIY weekend project or work that is being done by a professional, a house must be properly prepared in order to ensure that the new paint stays put for years to come. Here are some of the group’s most important tips for getting a home ready for a new, fresh coat of paint:

Inspect the house

Prior to getting to work on the paint job, the team at College Works Painting encourages a person to first do a quick spot test on the house. An individual should select an inconspicuous section of the home where paint is in rough shape. They should then clean and dry the surface and paint a small patch with the new paint. The next day, the individual can take a piece of tape and press it on the newly painted spot, quickly pulling it off. If the tape is clean, they know that it is safe to repaint after washing and prepping the house. However, if the tape yanks off all of the new paint with it, the house must get stripped before it can successfully be repainted.

Understand what kind of paint you are working with

It is common for an older home to be covered in oil paint. This means that applying a new coat presents the homeowner with one of two options: they can touch up what is already there, or choose to strip the home and start over. Periodic touch-ups work, but over time the paint will oxidize and become brittle. When this starts to happen, the individual can scrape off the spots that are peeling, prime the bare areas, and repaint with a latex paint. Over time, the areas that were not scraped will begin to peel, and the process will need to be repeated. Eventually, the entire house will be covered with a durable latex paint that sticks well.

Some people prefer to do the entire job at once, instead of waiting until the paint begins to peel to get to work. To do this, an individual can strip the house down to bare wood and repaint using a latex paint. Though this option requires more of an upfront investment, the professionals at College Works Painting explain that it can actually prove to be the more efficient option. Instead of taking a Band Aid approach to the project, the work is done in one swoop. This saves time, and often money too.

Many people fail to consider just how much of an impact climate has on their house. College Works Painting explains that the area in which a house is located should guide the repainting process. For example, blistering, peeling, and wrinkling paint are typically caused by lots of moisture, heat, and humidity. In order to see a successful paint job, it is necessary to correct the moisture issue prior to moving forward with a painting project.

Regardless of whether the homeowner chooses to do all of the repainting at once or opts to do it in pieces over time, proper preparation is a must. A home that is unprepared will not hold paint well, and will probably require the individual to completely redo the work in the near future. Before setting to work, the individual should keep in mind that their home may contain lead paint. Lead paint was highly common until 1950, but was banned in 1978. If the house is covered in lead paint, it is important that the homeowner does not try to remove it on their own, as this can cause serious illness.

In order to do touch-ups properly, the team at College Works Painting recommends masking windows and doors with heavy plastic. They can then use a hook scraper to remove loose paint. Any remaining paint should be sanded so all that remains is a dull finish. All cracked caulking should be taken care of, and the home should be washed with a garden hose.

When it comes to taking care of mildew and mold that is firmly planted in old wood, College Works Painting recommends using a cleaning solution that contains a cup of bleach and a cup of trisodium phosophate, mixed with two gallons of water. Let the cleaning solution sit for half an hour, and then get to work rinsing it with a garden hose. Though it may seem tempting to use a power washer for the job, this can seriously damage old wood. Additionally, trying to simply scrape or sand mold and mildew away will be rendered ineffective.

College Works Painting states that while it may be inspiring and exciting to try to tackle an exterior painting project on the weekend, a homeowner should only take on this venture on their own if they feel certain that they know how to proceed. Doing so without proper training or knowledge can cause serious damage to the outside of a house, states the team at College Works Painting.
